When it comes to high-performance dump trucks like the Komatsu HD785-7, every component within the drivetrain must operate with precision and durability. One such crucial component is the differential side gear, also known as the final transfer gear, that delivers manipulated rotation from the differential to the axle shaft. The MASSCoT Gear P/N: 561-22-61431 (MTK22/61431) is specifically engineered for this purpose — providing strength, durability, and accuracy in every operation.
For mining operators and construction fleets seeking dependable performance and long-lasting quality, MASSCoT offers an excellent OEM-alternative for the Komatsu HD785-7 differential system.
What Does the Differential Gear Do?
The differential gear system is a critical part of the drivetrain in heavy-duty vehicles like the Komatsu HD785-7. It enables smooth power delivery to the wheels during straight-line motion and also allows for speed variation between the wheels when the truck turns.
Specifically, the 561-22-61431 gear receives rotational input from the spider gear, which adjusts rotational differences between wheels, and then transfers that energy directly to the axle shaft. This precise movement allows the vehicle to turn safely and efficiently, without excessive tire wear or drivetrain stress.
